Abstract

The invention provides a breakage protection device for a belt conveyor. The breakage protection device for the belt conveyor comprises a driving drum, a reversing drum and a conveyor belt sleeved therebetween, wherein a support is arranged above the conveyor belt; an upper pressing beam vertical to the upper end surface of the conveyor belt is arranged in the middle of the support; the other end of the upper pressing beam is connected with a piston end of an upper hydraulic oil cylinder; a lower pressing beam for pressing the lower end surface of the conveyor belt is arranged in the middle of the support; the other end of the lower pressing beam is connected with a piston end of a lower hydraulic oil cylinder; the upper hydraulic oil cylinder and the lower hydraulic oil cylinder are connected with a hydraulic pump station through oil pipes respectively; a sensor for detecting reverse running condition of the conveyor belt is arranged below the conveyor belt at an interval; a controller is connected at the output end of the sensor; the output end of the controller is connected with the hydraulic pump station. Before breakage of the conveyor belt, the conveyor belt is stopped so as to prevent a heavy load thereon from sliding down, so that a breakage accident of the belt conveyor running in an inclined way can be effectively prevented and the safety of mine production is ensured.

Description

technical field [0001] The invention relates to the technical field of coal mine equipment, in particular to a broken belt protection device for a belt conveyor. Background technique [0002] Belt conveyor is a kind of machine which is driven by friction to transport materials in a continuous manner. It is mainly composed of a frame, rollers at both ends of the frame and a closed conveyor belt tightly sleeved on it. It can transport materials on a certain conveyor line, from A material conveying process is formed from the initial feeding point to the final unloading point. It can not only transport broken materials, but also transport finished items. It can be used for horizontal or inclined transportation, and it is very convenient to use. It is widely used in various modern industrial enterprises, such as: underground roadways of mines, mine ground transportation systems, open pit mines and mineral processing plants. [0003] In the production of modern coal mines, belt ...
